As the author of two books on iPhone software development published by the prestigious IT published O’Reilly you would expect any iPhone / iPod Touch application by Jonathan Zdziarski would be of high quality. He does not disappoint with his ballistics calculator simply named “Ballistic”.

Quite frankly there are to many features to list so I will summarize coolest ones:

– Ballistics Library with over 1500 bullets. No need to go online to find ballistic coefficients.

– Automatic weather conditions. It uses the GPS to find your location and look up weather conditions online.

– If mounted on a rifle it can automatically calculate the angle and adjust measurements accordingly.

– Range log (see screenshot below).
